Photo Locations: Balboa Park - San Diego, CA, Alameda Plazas and Alice Keck Park Memorial Garden - Santa Barbara, CA, San Luis Obispo, CA and San Diego, CA
A delightful tree for mild winter climates. Its foliage is similar to a Redbud, and the orchid-like flowers are highly prized. It is most-often grown in southern California, as it is rather tender. Those grown in the northern central valley usually do not flower as profusely. It may require regularly scheduled light top-trimming (but not necessarily shearing) of vigorous top shoots to maintain its height below 25'.
Has fragrant Flower.
Native to India and China.
